Just lost the brakes on the GP last night (single system). Made it home safely by downshifting the trans and with what little brakes I had left, but getting the car in the garage was a challenge!!

Ok - so I've gathered all the parts and have started the teardown....and already hit a couple snags.

a) I'm using the Autozone M-1328 master cylinder for a '69 Bonneville. I've added the adpater fittings to the outlets and, when I position the master cylinder, I've got hard contact with the wheelhouse inner. There's not enough room to add a brake line and make the turn. Anybody else experience this?

b) The removed single pot master cylinder has a very deep bore in the piston for the push rod; the new master cylinder has just a small dimple to position the push rod. I'll need to take quite a bit off the push rod but - how does it come out from the booster? When I pull on it it comes out a bit but feels like it is attached to a/the diaphram and sucks back in when I let go.

c) I sent a note to one of the brake engineers relative to the port placement. He was off for the GM shutdown but I'll let you know once he replies.

d) Do you all have a preference - should I keep posting here or should I start a new thread specific to my conversion?
